We are given the equation of a line
y = -2x + 1
We have to find the value of y at three different values of x i.e. x = 0, -3 and 1
In order to find the value of y at any given x, simply replace x by that number.
So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)
Similarly for x=-3, we get
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)
And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y = -1
This can be expressed as an ordered pair as (-1, -1)
For The First Question a Part Do You Need a Graph ?
He should use an average of 20%, and I'm assuming, since not enough info is given, that 1 gallon of milk has the given stats. The average of 20% would mean that he needs to have a 2/3 ratio of 18 to 24, because 18:24 = 6:8, which equals 2:3, so, therefore, he needs to have 42/5 = 8.4, then 8.4*2, 9.4*3 = 16.8 and 28.2, respectively, and if you add those, you get 42.
Hope this helps and have a nice day:)
Answer:
Step-by-step explanation:
The equation is given to be : -6 + 4x = 8
Now, we need to solve this equation in order to find the value of x
⇒ -6 + 4x = 8
Adding +6 on both the sides
⇒ -6 + 4x + 6 = 8 + 6
⇒ 4x = 14
dividing each term by 4
